PROCESS OF FINISHING WOOD SURFACES.

No Drawing.

surface and treated to obtain the polished and finished effects, the grain of the wood is caused to distinctly appear so that it is more visible than when seen in the natural state of the wood; and an object of this invention is to provide a simple and easy process whereby highly polished and finished effects embodying great visibility of the grain of the wood can be obtained with a minimum amount of material, labor and time.

To that end I employ a composition of matter including a mixture of flat white or white lead, graphite, pure turpentine, boiled linseed oil, and gasoline, one or more coats of which can be applied to the surface of wood and then treated to obtain the highly polished and finished effects and render Visible the wood grain.

Preferably the ingredients of this composition are used in about the following proportions: 5 quarts of flat white or white lead; 1 A pounds of graphite; 2 quarts of pure turpentine; 1 quart of boiled linseed oil; 1. quart of gasoline.

It is to be understood that when a larger or smaller amount of the composition is to be employed the volume of the ingredients will be increased or decreased proportionately.

The process consists in preparing the wood surface to be treated by first sponging it with water; then letting it dryythen sandpapering the surface and dusting it wit-h a cloth; then applying with a brush or other appliance a'coat of the foregoing described composition of matter, after which the coated surface is allowed to dry from four to eight hours; then the surface is sand-papered to give it a preliminary polishing and to make. distinctly visible the grain of the wood; then the surface is finished by a final polishing with a. cloth, preferably a woolen rag.

VVhilethe foregoing described process includes preliminary preparation of the wood surface by first spon 'ing it with water, then drying, sand-papering and dusting it, it is understood that these preliminary steps can Application filed August 20, 1925. Serial No. 51,512.

be dispensed with and the wood surface is clean or has previously been prepared.

As previously stated the process can, if lesired, include applying more than one coat of the composition of matter to the wood surface; and also if so desired various colors, including metallic tints, can be included in the composition of matter and in the process'employed.

W hen, however, an additional coat of the composition is to be added to the wood surface, the first coat is not finally sand-pa pered and polished until the second coat is added and dried; and if so desired a. much smaller proportion of graphite can be employed in the second coat. In other words the proportion of the ingredients for a second coat of the composition of matter is about as follows: 5 quarts of fiatwhite or white lead, et'ounces of graphite, 2 quarts of pure turpentine, 1 quart of boiled linseed oil,

1 quart of gasoline.

The second coat of the composition of matter is then applied with a brush or other appliance over the first coat and is then per mitted to dry; then the double coated surface is sand-papered and polished with a woolen rag as in the first instance.

As previously indicated, a variety of colors, if desired, can be added to the composition of matter to obtain various tints and color effects. In other words, if about 4 of an ounce of a color such as Prussian-blue is added to thecomposition of matter first referred to, and a wood surface finished therewith it will be colored a medium blue tint; and it is obvious, of course, that deeper or lighter shades of blue can be obtained by adding more or less of the Prussian-blue to the composition of matter. of the various wood tinting colors now in common use such as rose, pink, tan, brown. green, lavender and other colors including gold, silver and bronze finishes.

It is also understood that, if desired, the

composition of matter can be subdivided into portions; and then each portion colored clifferently so that when applied to a wood surface with a sponge 1a mottled and varied color-effect can be obtained. When a wood surface is so treated and the mottled coating has dried it is sand-papered and then polished with awoolen rag substantially as previously described.

This process is adapted to finishing either new or old wood-work, and when used in This is also true connection with refinishing the surfaces of old Wood-Work the antique appearance thereo't can he preserved and if desired the Wood surface can he made to appear as new.

The invention claimed is:

1. The process 01:: finishing a Wood surface consisting of applying a coat of a coinposi tion of inatter to a Wood surface, comprising a mixture of 5 quarts of fiat White or W iite lead, 1% pounds of graphite, 2 quarts of pure turpentine, 1 qut of oil and 1 quart of gasoline; then pern'iitting the coated Wood surface to dry then sand-papering the coated Wood surface to make the Wood grain visible; and then polishing the coatec Wood surface.

The process 0t finishing a Woed surface consisting of first cleansing; the Wood surface;

the mottled woodsur'taee then preparing acoinposition of matter comprising 5 quarts of flat white or White lead; 1 quarts of graphite; 2 quarts of pure turpentine, 1 quart of oil, and 1 quart of gas0- line; then separating the mixture into two or .more portions, then adding diiterent colors to each portion to obtain desired tints; then utilizing a-sponge to eqaplythedifierent tinted mixtures to Wood surface to ob- "ain mottled effect; then permitting the mottled "wood surface to thy; hen sandpapering the mottled Wood'surtace to make the Wood grain-visible; and then polishing With a Woolen cloth.
